Details

http-cache semantics contains an Inefficient Regular Expression Complexity , leading to Denial of Service. This affects versions of the package http-cache-semantics before 4.1.1. The issue can be exploited via malicious request header values sent to a server, when that server reads the cache policy from the request using this library.
